To all whom it Huey concern.-

Be it known that: I, Ema JAGENBERG, a sub1ect of the German Emperor, residing at Dusseldorf, Germany, have invented new;

and useful Improvements in Machines for Making Paper Boxes, of which the following is a specification.

This invention relates to a machine for folding and asting the creased blanks of an ular paper oxes of the class which are laid lnto a folded shape during their manufacture.

In the accompanying drawings, Figure 1 is a side elevation of my Improved machine for foldin and asting paper boxes. Fig. 2 is a plan thereo Fig. 3, a detail vertical section through the folding mechanism; Fig. 4, a plan of Fig. 3. Figs. 5 and 6 are details of the i folders.

The letter 0. indicates the driving-pulley of the machine, the shaft 1) ofwhich is intergeared with a series of prcssuro-rollcrs (1. One of the latter carries a disk a, which by a belt or otherwise drives roller This roller serves to impart motion to an endless elastic feed-apron g, by means of which the blanks A are carried forward. Above the apron g is arranged a. perforated guide or core plate 1'. between wlilchjaiid the apron a passage for the blank is formed, such blank projecting laterally beyoiftl the platc. The plate i is provided wit haan eye 1 that is clamped to a transverse rods, so that theplatc is laterally adjustable tl'lcr con. To the latter is secured a lever 1,"\\'hic-h'is drann downward by a spring *2. This spring tends to turn the rod 8 in the direction of the arrow, Fig. 3%, so that plate 'i is held with considerable pressure against.- the apron. Within the opcnings of plate i are jolu'nahgd number of guidcv ilanked by a pair of folders 7c lc",

rollers i, which arc adapted to engage the central portion of the blank. The plate 1' having curved flanges which arc so n'o'lilcd that they first turn up the sides of the blank and then successively fold them against the top of" the plate. Folder lc is longer than foldcr le and projects with its working or forward end beyond the latter, Fig. 4, so that folder it engages one side of the box and starts to turn the same down before folder If engages the opposite side of the box. In this way the ends of the box, which have been previously provided with a layer of adhesive, are made to overlap. After clearing the folders is these overlapped ends are subjected to the pressure of a spring-influenced roller 71-, j ournaled in a bearing 1), that. is laterally adjustable upon a transverse rod 0. 3y the lateral adjustment of bearing p and roller 72- the latter may be alined with the glued strip of blanks of different widths. From roller h the folded blank passes between the rollers d and an upper cooperating set of rollers (Z, by which the folded blank is compressed. The upper rollers d are journaled in hinged arms d to permit the rollers to be readily cleaned.

Having now fully described-my invention, what I claim as new. and desire to secure by Letters ,latcnt'. is"

1. In a nntchinc for making paper boxes, a pair of folders having curved flanges of different lengths. a feed-apron intermediate the folders and overlapped by the folder-flanges. a pivoted core-plate having an cye and a central row of openings. a rod embraced by the eye,- rollcrs ornna-lcd in the openings and adapted to engage the central portion of the blank, and means for pressing the rollers against the blank, substantially as specified.

2. in a machine for making pa )Ll' boxes. an endless elastic feed-apron, coin )lIlCLl with a. superposed. guide-plate having a series of openings and an eye, rollers onrnalc d 1n the opcnings,-a rod embraced by the cycf a lcver projcctiiig from the rod, and means for deprcssing flu lcvcr, substantially as specified.
